According to the World Health Organization, particulate matter affects more people than any other component of air pollution. Inhalation of these types of particles can cause a variety of possible effects ranging from irritation, infection and discomfort to exacerbation of asthma. Smokers or individuals with pre-existing conditions, such as heart or lung disease, may experience additional or more severe symptoms. Long-term exposure has been associated with an increased risk of developing cardiovascular and respiratory disease and even lung cancer.
Refer to our document on Respiratory Protection for Exposures to Particulate Air Pollution (PDF, 61KB) for more information on risks and possible protection options to help protect people from harmful effects of air pollution.
